Land Use Change and its Impact to Marine Primary Production in Semarang Waters

AbstractIn this study, copper oxide (CuO) thin films were deposited by chemical solution deposition (CSD) method with layer variation to observed and determined crystal structure and optical properties of CuO films. The crystal structure of films were characterized by X-ray diffraction (XRD). The optical properties were studied with annealing temperatures 350°C, 450°C, and 550°C by spectrophotometer VIS-NIR. Absorbance spectra showed that CuO film has absorbance in the visible region. Band gap energy of CuO is found to decrease from 2.05 – 1.89eV as a result of the increasing annealing temperature. The result of this study concludes that CuO thin film has the potential to be developed as solar cell on of LAPAN IPB satellite
